I own an older Kawasaki Bayou 300 4x4 ATV, and it has a continueing problem of not starting. The starter engages (It's newly replaced) but the spark doesn't seem to ignite the fuel. The spark plug seems fine, but has also been replaced. The wire from the spark plug has also been replaced. It only happens, it seems, whenever it feels like (One day it will start fine, the next day THIS happens). We've often believed it was a colonoid in the back of the machine, as a bad connector exists there, but I'm starting to think jiggling the wire doesn't actually have an effect. If anybody has any ideas on what could be causing the non-start, please answer. Be much appreciated.
